No bluetooth after update - MTCB Android Head Units Q&A

Hi guys.
I recently updated my unit to Malaysk 5.1 V3, but after update the bluetooth no longer works.
I tried Malaysk 5.1 V2 also, but with the same issue.
I also tried different MCU's, but that didnt help either.
I have tried all the bluetooth options in "Factory settings" without any luck.
As soon as i go stock it works again.
Does anyone have a fix for this problem?
My unit is made for BMW e90 from 2005 - 2011
My unit info is.
S07
MTCB-KGL-V2.80
Android version 4.4.4_07112015
rk3188-eng4.4.4 07112015
CPU Arm cortex-A9 @ 1.6GHz (x4)
Memory 1024MB

Is there really no one who can help, or know why this happends?????

I have the same problem same unit but no luck with 5.1.1 so for now staying on 4.4.4

Bluetooth Modul damaged?

Hi guys,
I am using an A-Sure Android Quad RK3188 radio with the latest Malaysk Firmware.
MCU Version is 2.83. A few months ago, Bluetooth worked from time to time.
Now it doesn´t find Bluetooth devices anymore – I don´t know why.
I also tried different firmwares..nothing helps
Maybe it´s damaged…would it possible to use another Bluetooth pcb?
If yes.. do you have any recommendations?
Thank you in advance..
Regards

Try changing BT type in Factory Settings. After FW updates id may change to other type by itself. Happened to me. It looks like if works (yes you can get in BT app and it shows like working but searching and connecting doesn't work).

Thanks for your reply. I tried several BT Types but nothing changes. (It is an A-Sure RK3188 Radio for Vauxhall)
I also tried several firmwares from Malaysk. The best one for me is from may 2016.
Does anyone tried to solder another bluetooth stack on the main pcb?
Thank you all in advance.

What is your phone Andorid ver? There is known bug on 7.1 (confirmed by Google) preventing pairing/connecting to car systems.

It doesn´t depend on the phone I think (I don´t use nougat version.) I tried it with different android phones - also with 3 OBD devices.

MTCC RK3188 KLD6 Bluetooth for calls problem

I'm looking for help to resolve my 'Head Unit to Handset' Bluetooth calling problem.
My handset is a Sony Xperia XZ Premium (G8141) running Nougat 7.1.1 (O2 Stock ROM build 45.0.A.5.1)
My head unit is an Autopumpkin 11-RQ0546-UK-A (MTCC RK3188) currently running Malaysk 5.1.1 ROM and KLD6 V2.83 MCU with Microntek Head Unit Service V2.18
My HU and Handset are paired and media audio plays fine (with the Bluetooth app open on the HU).
When the devices first connect the phone shows 'Connected for Media and Calls' and the HU bluetooth app shows all of the options available (media, calls, phone book etc) but only for 1-2 seconds then they all become unavailable and the phone changes to 'Connected for Media'. When my phone rings nothing happens on the HU and my phone does not show the bluetooth speaker option in the phone app.
This HU worked great for calls with my previous handset (Xperia Z3 Android 6) and I was running Malaysk 4.4.4 ROM but it wouldn't work with my XZ Premium so I tried the following: -
Malaysk 4.4.4 ROM with MCU KLD6 V2.83
Malaysk 5.1.1 ROM with MCU KLD6 V2.83, V2.85 & (even a KLD9 MCU by mistake)
Microntek HU Service as included in ROMS but also newest version from XDA thread (both Bluetooth settings from this app)
all different MCU System settings for Bluetooth that are available (about 5 or 6 from memory).
Nothing seems to make things work. Some settings disable the bluetooth altogether but mostly the same thing happens, connection with all options available for a few seconds then just media audio.
Due to the length of time required to flash various combinations of MCU/ROM/HU service/settings I was hoping that someone could suggest a quicker way to fix this?
Thanks for reading, Thintin
Nobody?
Update: my Xperia XZ premium has updated to android 8 and now Bluetooth works as expected.
I got Bluetooth calls to work
I have an Eonon GA5180F with a rk3188 processor. It came with Android 4.4. I wanted to upgrade it to add more apps. I used Malaysk's ROM 5.1.1. All was well, but the Bluetooth calls did not work. The bluetooth music worked. I fixed this by going to settings, then to factory settings, then entering code 126 (or what ever your factory code is), then going to application, to BT and then changing it from IVT_BT to WQ_BC6. I saved it and then rebooted. The calls worked after that.

Unstable Bluetooth Connection issue PX5 MTCD/MTCE Android 9

Hey guys.
I'm on a Xtrons TE103AP which is basically a PX5 MTCD/MTCE unit. I was previously on stock Android 8.0, had no issues with OBD Bluetooth pairing and running ECU based programs off of it. Moved to Malaysk's 8.0, no issues as well. MCU back then was the MTCD the unit came with, GS 2.71 if i remember correctly
I took the plunge and moved to Android 9, first with Hal9k's v4.0, then Stock Android 9 for GS units (the most recent release). I tried these 2 combinations with different MCU's from GS 3.00 right up to GS 3.44 (latest). While i'm able to pair with my BT OBD2 Adapter with no issues, i'm unable to maintain a connection. The bluetooth OBD icon on the task bar connects and randomly disconnects causing programs (torque and hybrid asst etc) to drop connections with the ECU.
The behavior is constant. I've tried changing selecting different bt drivers from the factory menu, to no avail.
Anyone can shed some insight?
Thanks!

What BT type? Is it still OK on Android 8?

Thanks for replying!
It was on WQ_BC6 by default. That was on android 8 (stock) and on Malaysk. I tried reflashing back to Android 8, but on the new MTCE MCU's. Problem persists.
Could it be the MCU causing issues? I've tried almost all the GS MTCE MCU's and they all produce the same issue.
Other Bluetooth functions work fine. A2DP and phone sync is perfect.

How have you tested your OBD adapter to confirm ithe adapter isn't the issue? Is it a genuine OBD adapter or knockoff?

Already tested. Its a rebadged ELM from Xtrons. They charged a premium for it, moreover it works fine on my android tablet. No connection drops or the sort. The exact same OBD was working fine with Android 8 as well prior.
A new update. I just realized that while i'm able to pair my phone and stream A2DP, and sync contacts with my phone, incoming calls route no audio or voice. Incoming calls trigger a prompt and i'm able to answer, but there's no sound or pickup from the microphone. weird....
I've tried selecting BC8 and BC6 in the factory settings... not quite sure what i'm dealing with. I'm on GS3.30bd, the BD modded MCU. Will see if an unmodded MCU fixes the voice issue.
@marchnz I flashed an unmodded GS 3.44 MCU and bluetooth audio worked properly. the OBD connection was still intermittently dropping. I then moved back a step to GS 3.40bd (soundpatched) and had no issues as well with bluetooth audio. I suppose the bluetooth issue was from the modded 3.30 MCU.
The Bluetooth OBD connection drop still hasn't been resolved however.
Any suggestions?

Is it an MTCD head unit. What does seller suggest when using hacky zlink
It looks like this. The seller doesn’t say anything no help. Is there an alternative to zlink?

If you're wanting to do Android Auto, there is an app called "Headunit Reloaded" developed by XDA developer @Emil Borconi. There is a free version of Headunit Reloaded that you can install to verify hardware compatibility before purchasing the full version. I have purchased the full version and can confirm that it works quite well as an alternative to ZLink.

I have a Android radio the uses the zlink app, that I use my apple carplay, this wireless connection is very unstable and drops regularly. sometimes it does not connect at all.
The cable is beter but does also just randomly drop.
I have tried other iphones, cables and even looked for newer firmware, but says we have latest version on.
I purchased the Carlinkit device to see if this will work but also no luck.
Can someone maybe advice me?

Use the android head unit as android head unit or buy genuine AA or Carplay unit based on need.
These Chinese knockoffs emulate and are problematic as emulator.
